springmvc+spring+mybatis整合实例【转】
开发环境:
System:Windows server 2003
WebBrowser:IE6+、Firefox3+
JavaEE Server:tomcat5.
IDE:eclipse、MyEclipse 6.5
Database:MySQL
开发依赖库:
JavaEE5、Spring 3.0.5、Mybatis 3.0.2、myBatis-spring-1.0.0-rc2
1、 首先新建一个WebProject 命名为ssi,新建项目时,使用JavaEE5的lib库。然后手动添加需要的jar包,所需jar包如下:
2、 添加spring的监听及springMVC的核心Servlet,web.xml内容,内容如下:
org.springframework.web.context.ContextLoaderListenercontextConfigLocationclasspath:applicationContext-*.xmlspmvcorg.springframework.web.servlet.DispatcherServletspmvc*.doCharacterEncodingFilterorg.springframework.web.filter.CharacterEncodingFilterencodingutf-8CharacterEncodingFilter/*index.jsp
3、 在WEB-INF目录中添加spmvc-servlet.xml,内容如下:
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
4、 在src目录下添加applicationContext-common.xml,内容如下:
classpath:com/hoo/mapper/*.xml
上面的配置最先配置的是DataSource,这里采用的是jdbc的DataSource;
然后是SqlSessionFactoryBean,这个配置比较关键。SqlSessionFactoryBean需要注入DataSource数据源,其次还要设置configLocation也就是mybatis的xml配置文件路径,完成一些关于mybatis的配置,如settings、mappers、plugin等;
如果使用MapperScannerPostProcessor模式,会自动将basePackage中配置的包路径下的所有带有@Mapper标注的Mapper(dao)层的接口生成代理,替代原来我们的Mapper实现。
5、AccountMapper接口内容如下:
@Mapper("mapper")publicinterfaceAccountMapperextendsSqlMapper {publicListgetAllAccount();publicAccount getAccount();publicAccount getAccountById(String id);publicAccount getAccountByNames(String spring);
@Select("select * from account where username = #{name}")publicAccount getAccountByName(String name);publicvoidaddAccount(Account account);publicvoideditAccount(Account account);publicvoidremoveAccount(intid);
}
6、 实体类和account-resultmap.xml
privatestaticfinallongserialVersionUID = -7970848646314840509L;privateInteger accountId;privateInteger status;privateString username;privateString password;privateString salt;privateString email;privateInteger roleId;//getter、setter@OverridepublicString toString()
{returnthis.accountId + "#" +this.status + "#" +this.username + "#" +this.password + "#" +this.email + "#" +this.salt + "#" +this.roleId;
}
account-resultmap.xml
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">username, passwordinsert into account(account_id, status, username, password)
values(#{accountId}, #{status}, #{username}, #{password})select cast(random() * 10000 as Integer) a from #Tabinsert into account(account_id, status, username, password)
values(#{accountId}, #{status}, #{username}, #{password})update account set
status = #{status},
username = #{username},
password = #{password}
where account_id = #{accountId}delete from account where account_id = #{id}
7、 在src目录中添加applicationContext-beans.xml内容如下:
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
这里配置bean对象,一些不能用annotation注解的对象就可以配置在这里
8、 在src目录中添加mybatis.xml,内容如下:
在这个文件放置一些全局性的配置,如handler、objectFactory、plugin、以及mappers的映射路径(由于在applicationContext-common中的SqlSessionFactoryBean有配置mapper的location,这里就不需要配置)等
9、 定义AccountDao接口及实现代码,代码如下:
publicinterfaceAccountDao{publicbooleanaddAccount(T entity)throwsDataAccessException;publicT getAccount(Integer id)throwsDataAccessException;publicList getList()throwsDataAccessException;
}
接口实现
importjava.util.List;importjavax.inject.Inject;importorg.springframework.dao.DataAccessException;importorg.springframework.stereotype.Repository;importorg.springframework.beans.factory.annotation.Autowired;importcom.hoo.dao.AccountDao;importcom.hoo.entity.*;importcom.hoo.mapper.*;importorg.springframework.beans.factory.annotation.Qualifier;
@SuppressWarnings("unchecked")
@Repository("accountDaoImpl")publicclassAccountDaoImplimplementsAccountDao{
@Autowired(required=false)
@Qualifier("mapper")privateAccountMapper mapper;publicbooleanaddAccount(T entity)throwsDataAccessException {booleanflag=false;try{
mapper.addAccount(entity);
flag=true;
}catch(DataAccessException e)
{
flag=false;throwe;
}returnflag;
}publicT getAccount(Integer id)throwsDataAccessException {
T entity=null;try{
entity=(T)mapper.getAccountById(String.valueOf(id));
}catch(DataAccessException e)
{throwe; }returnentity;
}publicList getList()throwsDataAccessException {return(List)mapper.getAllAccount();
}
}
10、 服务层AccountBiz接口及实现代码
接口:
publicinterfaceAccountBiz{publicbooleanaddAccount(T entity)throwsDataAccessException;publicT getAccount(Integer id)throwsDataAccessException;publicList getList()throwsDataAccessException;
}
实现代码:
packagecom.hoo.biz.impl;importjava.util.List;importorg.springframework.dao.DataAccessException;importcom.hoo.biz.AccountBiz;importcom.hoo.entity.*;importjavax.inject.Inject;importcom.hoo.dao.*;importorg.springframework.stereotype.Service;importcom.hoo.exception.BizException;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.beans.factory.annotation.Qualifier;
@Service("accountBizImpl")publicclassAccountBizImplimplementsAccountBiz{
@Autowired
@Qualifier("accountDaoImpl")privateAccountDaodao;publicbooleanaddAccount(T entity)throwsDataAccessException {if(entity==null){thrownewBizException(Account.class.getName()+"对象参数为empty!");
}returndao.addAccount(entity);
}publicT getAccount(Integer id)throwsDataAccessException {returndao.getAccount(id);
}publicList getList()throwsDataAccessException {returndao.getList();
}
}
11、 springMVC的控制器,AccountController代码如下:
packagecom.hoo.controller;importjavax.inject.Inject;importjavax.servlet.http.HttpServletRequest;importorg.springframework.stereotype.Controller;importorg.springframework.ui.Model;importorg.springframework.web.bind.annotation.ExceptionHandler;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.RequestParam;importorg.springframework.beans.factory.annotation.Autowired;importcom.hoo.biz.AccountBiz;importcom.hoo.entity.Account;importorg.springframework.beans.factory.annotation.Qualifier;
@Controller("accountController")
@RequestMapping("/account")publicclassAccountController {
@Autowired
@Qualifier("accountBizImpl")privateAccountBizbiz;
@RequestMapping("/add")publicString add(@RequestParam String username, @RequestParam String password, @RequestParam String status)
{
Integer stat=Integer.valueOf(status);
Account acc=newAccount(username,password,stat);
System.out.println(acc);
biz.addAccount(acc);return"redirect:/account/list.do";
}
@RequestMapping("/get")publicString get(Integer id,Model model)
{
System.out.println("###ID:"+id);
model.addAttribute(biz.getAccount(id));return"/show.jsp";
}
@RequestMapping("/list")publicString list(Model model)
{
model.addAttribute("list",biz.getList());return"/list.jsp";
}
@ExceptionHandler(Exception.class)publicString exception(Exception e,HttpServletRequest request)
{
request.setAttribute("exception", e);return"/error.jsp";
}
}
12、 基本页面代码
index.jsp
整合springmvc3.2+spring+mybatis3.2
查询所有添加
查询
List.jsp
<%@ page language="java"import="java.util.*"pageEncoding="utf-8"%><%@ taglib prefix="c"uri="http://java.sun.com/jsp/jstl/core"%>My JSP 'list.jsp' starting page-->id:${data.accountId }--name:${data.username }--password:
${data.password }
show.jsp
${account }
${account.username }#${account.accountId }
error.jsp
Exception:${exception }
<% Exception ex=(Exception)request.getAttribute("exception"); %>
<%ex.printStackTrace(new PrintWriter(out)); %>
13、 以上就基本上完成了整个Spring+SpringMVC+MyBatis的整合了。如果你想添加事务管理,得在applicationContext-common.xml中加入如下配置:
同时还需要加入aspectjweaver.jar这个jar包;
注意的是:Jdbc的TransactionManager不支持事务隔离级别,我在整个地方加入其它的TransactionManager,增加对transaction的隔离级别都尝试失败!
也许可以用于jpa、jdo、jta这方面的东西。
